Interesting info and product (thanks to detective work by levitize) .
Moog are one of thee largest USA suspension manufacturers, part no K750069.
U can buy two of these inc freight for less than half of one OEM links.(ridiculous) !!!!
An issue has arisen with the instalation of aftermarket rear sway bars (extra torque being applied to OEM links) and then failure !!!!!.
This issue has been well documented on diff Mazda forums around the globe and this heavy duty product seems the answer, thicker stem ,grease nipples ,locking nuts instead of allen key /way, and bronze ball and cup instead of oem plastic, 2 yr warranty.
I have ordered and will follow up with further info when installed.
